Cruise Inventory Information

Long name RRS James Cook (740H) cruise JC011
Short name JC011
Objectives and Narrative This was the first cruise undertaken as part of the NERC-funded consortium project (NE/C512961/1) entitled ECOMAR - Ecosystem of the Mid-Atlantic Ridge at the Sub-Polar Front and Charlie Gibbs Fracture Zone. ECOMAR - Ecosystem of the Mid-Atlantic Ridge at the Sub-Polar Front and Charlie Gibbs Fracture Zone.

ECOMAR forms part of the Census of Marine Life MAR-ECO project which is an international study of life in the northern mid-Atlantic Ocean with scientists from 16 nations participating in research of the waters around the mid-Atlantic Ridge from Iceland to the Azores.

Depart: Empress Dock, Southampton, UK, Friday 13 July 2007
Sonar Calibration: Bantry Bay Ireland, Sunday 15 July 2007
Long term moorings were placed at four super stations at a bottom depth of 2500m equipped with sediment traps, current meters, ADCP and sensor suites, SE - 49 01.92 N, 27 40.82 W, SW - 48 46.80 N, 28 38.43 W, NW - 53 59.33 N, 36 07.39 W and NE 54 00.05 N 34 10.61 W. Swath bathymetry surveys mapped 1500 square miles along two transects across the ridge between these stations at ca. 49 N and 54 N. Video and still images of the sea floor were obtained during 5 SHRIMP vehicle tows and 9 lander deployments. Faunas samples were taken with 9 megacorer casts, 7 bottom trawls, 4 baited traps and 8 mid-water trawl tows. 58 CTD casts investigated water masses, flow and primary productivity over the ridge and along a line between the southern and northern stations coinciding with the TOPEX-Poseidon satellite altimeter track. EK60 acoustic surveys quantified pelagic biomass and optical remote sensing measured patterns of primary productivity and locations of fronts. Seabird and cetacean observations were made throughout the voyage with acoustic recording of cetacean sounds. A long-term platform, DOBO with cameras and a cetacean sound recorder was deployed at 3690m depth in the Charlie Gibbs Fracture Zone.
Sonar Calibration: Brodick Bay, Arran, UK, Friday 17 August 2007
Arrive: Fairlie Pier, by Largs, Firth of Clyde, UK, Saturday 18 August 2007

The ECOMAR area will be revisited by the RRS Discovery in summer 2008 and the RRS James Cook with the ISIS ROV in 2009.
